speincationof Letters Patent. Patented Dec. 18, 19.17.V

Application led July 25, 1913.V SerialNo. 7181,153.

To all whomit may concern: t Y Y ABe it lmowgfthat I, EDWARD J. RENKEN- f BERGER, a citizen of the UnitedStates, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements Yin Reinforced Wire F errules for lVooden Handles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. y

My invention relates to tool handles, and

has for its' object to provide a reinforcing wire ferrule for the handle which will afford protection and impart increased strength to the face-end of the tool receiving portion of the handle and at the same time permit the ferrule to the rear of the face-end to expand and contract to conform to irregularities in the handle with the view of maintaining the tension-grip of the wire coils on the handle and prevent or restrain the tendency to split the handle by forcing the tool into place. Also to provide what for convenience may be .termed a buttress at the face-end of the handle so that when it is hard to remove the handle from the tool' blows may be imparted to the face-end of the handle `without injury to the handleor ferrule. t

To the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter particularly described and then sought to be clearly defined by the claims, reference being had to the accompanying 40 drawing forming a part hereof and in which Figure 1 is a longitudinal section through a handle and ,ferrules illustrating one form of the invention;

In the drawing the numeral 1 designates a wooden handle which may be of any approved coniguration and as illustrated is formed with a swell 2 near the front end and with a central borel 3 to receiveV the' tang ofthe tool to which the handlemay be attached. The handle is formed at its tool receiving end with a reduced central por'- tion 4 and a shoulder 5 at the base of the reduced portion, and with a shoulder 6 adjacent or next to the gripportion of the handle.

The ferrule 7 is formed of wire of any preferred form in cross section but preferably round and has one end secured to the tool receiving end of the handle and the other end to the handle at or adjacent to the grip portion of the handle, the intermediate portion vof the wire strand being wound tightly under considerable tension around the handle but the convolutions left unattached from each other and from the handle except where they encircle the reduced portion in front of the shoulder vat the tool receiving end and at the point where the end next to the grip portion is secured to the handle. to expand andcontract under the variations in the diameter of the handle due either to expansion eausedby driving the tool tang in stricted but also an adjustmentvof the coilsto the changing conditionsbe provided for.

Inorder to most securely hold the Aend of the Wire ferrule to the tang recevngend of the handle andy also to afford a strong protection to that end 4and likewise provide a stabley buttress to receive the blows forA disengaging tlfievhandle and tool tang when there is an exceptionally tight fit between This enables the wire ferrule.

the two parts, the end of the wire is pro.-

vided with afprong 8' to enter the reduced end portion of the handle vand then the wire is Wound tightly around'the reduced portion 4 in layersfor to forma series of adjacent superimposed Y c'yonvolntions,` 9 between the shoulder 5 vand therv end of the reduced portionr4 as illustrated` inFigs. 1,2 and 3, and then continued ina convolute manner around Vthe handle to the point where the other end of the wire is secured to the handle at or adjacent to the grip portion by a prong l0 embedded in the handle and at such point secured to the adjoining convolution by a drop of solder 1l.V The first convolution from the prong 8 may proceed directly around the reduced portion 4 as illustrated in F ig. l but it is preferred to provide a straight portion or Abend Vl2 extending parallel with the surface of the reduced portion 4, and preferably embedded so as te lie flush with the surface, as indicated in Fig. 2 of the drawing, the straight portion extending from the prong to the shoulder 5, or the prong may be next to the shoulder andthe straight portion 18 extend toward the 4end of the reduced portion as indicated in Fig. 3. In either case the superimposed and adjacent coils extend across the straight portion of the wire and tend to hold it in place,

and as onD or more oi the superimposed coils will bear against the shoulder el end thrust against the end of the handle is re sisted and the coils prev vited from beingl forcibly dislodged or moved from position.

To protect the superimposed adjacent coils around the reduced end a of the handle, a band or cap of solder lei Vis applied across the outermost superimposed coils and also over the topmo'stcoils of the series of adjacent coils, thus securely fastening the coils together at such points of contact as well as protecting the coils and together with the coils forming a stable buttress to receive the blows of a hammer for detaching the handle and tool in the event of the tive having an exceptionally tight fit to each other.

Having described my invention and set forth its merits what l claim is l. A handle and reinforcing wire ferrule encircling the handle, one end'of the wire being attached to the tool end of the handle and the other end to the handle toward its grip portion, the errule being formed of coils with those at the tool receiving end arranged to constitute a series of adjacent superimposed concentric convolutions, substantially as described. v

2. A handle and reinforcing wire ferrule encircling the handle, one end of the wire being attached to the tool end of the handle and the other enti to the handle toward its grip portion, the ferrule being formed of coils with those at the tool receiving end arranged to constitute superimposed concentric convolutions, substantially as described.

3. A handle and reinforcing wire ferrule consisting orp the handle having at its tool receiving end a reduced portion and a shoulder at the base of the reduced portion, and a wire ferrule encircling the handle, the opposite ends of the wire being attached to the handle, and the wire at the tool receiving end being wound around the reduced portion of the handle to form a series of adjacent superimposed convolutions between the shoulder at the base of theH reduced portion I and the outer end of the latter, substantially as described. Y

4f. A handle and reinforcing wire ferrule consisting of the handle having at its tool receiving end a reduced portion and arshoul der at the base of the reduced portion, and a wire ferrule encircling the handle, the opposite ends of the wire being attached to the handle, and the wire at the tool receiving end having a part bent to lie parallel with thersurface of the reduced portion and also wound around saidk portion transverselyVV across the bent portion of the wire to Jform t a series of adjacent superimposed convollr tions overlying the bent portion between the shoulder at the base of the reduced portion and the outer end of the latter, substantially as described.

5. A handle and 'reinforcing wire fer-rule-.

consisting of the handle having at its tool 'receiving end a reduced portion and a shoulder at the base of the reduced portion, a. wire ferrule encircling the handle and having its opposite ends attached thereto, the

wire at the tool receiving end being woundy around the reduced portion to forni a series of adjacent superimposed convolutions between the shoulder at the base of the reduced portion and the outer end of the latter, and

a metallic cap applied across the outermost superimposed end coils and over the topmost coils of the series of adjacent coils, substantially as described.

6. A handle and reinforcing wiie ierrule consisting of the handle having at its tool receiving end a reduced portion and a shoulder at the base of the reduced portion, a

wire fel-rule encircling the handle and hav-V ln testimony whereof I aliix my signature in presence of two witnesses.
